WINDOW-SCREEN FRAME.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed 0ctobe/r/2, 1919. Serial No. 327,979.

To all whom it may concern: I

Be it known that I, Rose ZREBIEC, a/citizen of the United States,residing at oodlawn, in the county of Beaver and State of Pennsylvania,have invented certain new and useful Improvements in VVindow-ScreenFrames, of which the following is a specification.

This inventionrelates to new and useful improvements in frames forwindow screens and the primary object thereof is to provide a device ofthe character described and in a manner as hereinafter set forth whichmay be readily and conveniently attached to ordinary window flyscreening and form a very substantial structure.

Further objects of this invention are to provide a frame for windowscreens which is simple in its construction and arrangement, strong,durable and eflicient in its use and comparatively inexpensive tomanufacture.

To the accomplishment of these and such other objects as may hereinafterappear the invention-consists of the novel construction, combination andarrangement of parts herein specifically described and illustrated inthe accompanying drawing, wherein is shown an embodiment of theinvention, but it is to be understood that the device shown is merelyillustrative and that various changes in the form, proportion and minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of th invention, whichcome within the scope o. the claims hereunto appended.

In the drawing forming aportion of this specification and wherein likenumerals of reference designate corresponding parts throughout theseveral views:

Figure 1 is an elevational view of a window screen, including a frameconstructed in accordance with this invention.

Fig. 6 is a sectional view on line VI-VI, Fig. 5.

Fig. 7 illustrates the end of the frame member in the expanded position.

Fig. 8 is a sectional view on line VIIL VIII, Fig. 2.

Fig. 9 is a fragmentary view showing the method of securing the cornersof the frame to ether.

eferring more in detail to the drawing there is shown in Fig. 1 a windowfly screen in accordance with this invention and comprising theforaminous body or screening 1, the frame end members 2 and 3, and theframe side members 4: and 5.

The-construction of the frame end members 2 and 3 and the frame sidemembers 4: and 5 is identical, and the former may vary in length withrespect to the latter to drawing, to form the inner and outer walls 6and 7, respectively.

The edges 8 and 9, of respective walls 6 and 7 of the frame members,with the eX- ception of respective end portions 10 and 11, thereof, areturned inwardly upon the in ner face of the walls 6 and 7, and areprovided for the purpose of substantially rethe frame members.

The edge 8, of the wall 6, is formed with a plurality of teeth 12, thepoints 13 of which, when engaging the screening 1 as shown in Figs. 3and 4:, stand slightly away from the inner face of the wall 6, and whennot used to secure the screening 1, lie flatly against the inner face ofthe wall 6.

The edge 9, of the wall 7, is likewise formed with a plurality of teeth14, the points 15 of which either lie flatly against the inner face ofthe wall 7 or stand slightly away therefrom, depending on whether or notsaid teeth 14: are utilized for securingthe screening 1 therein.

For the purpose of securely clamping the walls 6 and 7, forming theframe member, together after thescreening lhas been engaged-b either theteeth 12 or 14, certain of the teet 1 12 and 14 are adapted to be bentat right angles with respect to their respective walls and register withand extend through slots 16 or 17, respectively formed in the walls 6and 7, after which said teeth are clenched to clamp said walls securelytogether.

Teeth are provided on the inner face of both of the walls 6 and 7, sothat after many of the teeth on one wall have been broken or becomeunfit for use, due to changing the screening therein, the teeth of theother wall may be used, thereby dou- 1lgling the life and utility oftheframe memers. 1

Each end of the frame members'is formed with the elongated end portion1Q and a short end portion 11. A slot is for ied intermediate of the endportions 10 and 11 and is of a length commensurate to the width of theframe member when fo ded together longitudinally as herein beforelescribed.

.F or securely connecting the frame members together the elongated endportion 10 of the side frame member passes through the slot 18 in theend frame member, while the elongated end portion 10 of the end framemember passes through the slot 18 in the side frame member, after whicheach of the elongated end portions is bent over to overlap its short endportion, as shown in Figs. 8 and 9 of the drawing.

It will here be noted that a screen frame constructed in accordance Withthis invention may be readily and conveniently assembled, and brokenscreening easily replaced therein, and may be attachedto the windowframing, if desired, in any suitable manner. A

What I claim is 1. A screen frame comprising a plurality of framemembers, each of which consists of a strip of bendable metallic materialbent at its longitudinal center upon itself a and further having eachlongitudinal mar ginal portion thereof bent inwardly and. provided withfastening barbs, said strip at each side of its longitudinal center proend slitted to form a pair of bendable end greater length than the'portions one of other.

In testimony whereof I affix my signature.

ROSE ZREBIEC.
